Redefining recycling sorting technology with Australia’s first AI-powered robot

A robot that uses artificial intelligence to sort used Tetra Pak beverage cartons has been installed at APR Kerbside’s Material Recovery Facility (MRF) in Truganina, Victoria. Aimed at advancing the circular economy, this innovative recycling sorting technology has been funded via a joint investment between Tetra Pak and APR Kerbside. As part of APR’s future plans, aspirations for upgrade and expansion include the opening of new Material Recovery Facilities in Victoria and the commissioning of additional AI-powered robots to be rolled out over the next two years. In an Australian first, food and beverage processing & packaging company Tetra Pak has partnered with (Australian Paper Recovery (APR) Kerbside to implement an AI robot that can identify, and sort used Tetra Pak beverage cartons. The robot has been commissioned at the APR Kerbside Material Recovery Facility (MRF) in Truganina, Victoria. This glass-out facility has the capacity to process up to 20,000 tonnes of materials annually and mainly sorts items from the kerbside stream. Such items collected from residents’ yellow lidded recycling bins include paper and cardboard, steel, aluminium, plastics (bottles and containers). The robot has been training, learning to recognise all the different types of beverage cartons, like milk, soy, oat, almond, stock and juice ahead of its final deployment in the coming weeks. The councils that are working with APR Kerbside are excited about this opportunity to divert more valuable resources from landfill. They are eager to expand the current kerbside service offering to their respective residents. Darren Thorpe, Managing Director of APR Kerbside. Vikas Ahuja, Sustainability Director at Tetra Pak Australia and New Zealand said: “Tetra Pak is incredibly proud to be pioneering this exciting recycling innovation with APR to further advance the circular economy in Australia. For us at Tetra Pak, to be the first market outside […]

New CSIRO research explores influence of coal seam gas activity on human health

New research has been released into the potential for coal seam gas (CSG) activity in Queensland to affect human health. A 2,150 square kilometres study site in the Surat Basin, Queensland, was selected and factors that could lead to potential hazards such as chemicals, air emissions, noise, light and dust associated with CSG activities were identified and appraised. Existing data related to these factors was screened to determine whether any factors would require in-depth assessment. While the study found that for the majority of factors there was no plausible pathway to impact human health, it determined further in-depth assessment of a small number of identified factors was required. As a result, two new CSIRO research projects are now underway and will conduct further in-depth studies focussing on eight groups of chemical factors. The research, undertaken by CSIRO and The University of Queensland, was governed through CSIRO’s Gas Industry Social and Environmental Research Alliance (GISERA). GISERA is an alliance led by CSIRO and is a collaboration between CSIRO, commonwealth, state and territory governments and industry with the purpose of working with the community to undertake research about the potential or actual impacts of gas development, across major environmental and socio-economic topics. The study was funded primarily by the Queensland (59 per cent) and Federal Governments (21 per cent) and CSIRO (18 per cent). GISERA industry partners APLNG and QGC each provided one per cent in funding and also made available operational data. CSIRO Energy Resources Research Director and GISERA Director Dr Damian Barrett said the study provided forensic information about the potential hazards to affect human health from CSG activities in the Surat Basin. “The value of this exhaustive study is that it provides certainty about where we need to focus further research,” Dr Barrett said. “By ruling out factors of […]

Australia hasn’t figured out low-level nuclear waste storage yet – let alone high-level waste from submarines

Ian Lowe, Emeritus Professor, School of Science, Griffith University Within ten years, Australia could be in possession of three American-made Virginia-class nuclear submarines under the AUKUS agreement with the United States and United Kingdom. The following decade, we plan to build five next-generation nuclear submarines. To date, criticism of the deal has largely focused on whether our unstable geopolitical environment and China’s military investment means it’s worth spending up to A$368 billion on eight submarines as a deterrent. But nuclear submarines mean nuclear waste. And for decades, Australia has failed to find a suitable place for the long-term storage of our small quantities of low and intermediate level nuclear waste from medical isotopes and the Lucas Heights research reactor. With this deal, we have committed ourselves to managing highly radioactive reactor waste when these submarines are decommissioned – and guarding it, given the fuel for these submarines is weapons-grade uranium. Where will it be stored? The government says it will be on defence land, making the most likely site Woomera in South Australia. What nuclear waste will we have to deal with? Under this deal, Australia will not manufacture nuclear reactors. The US and later the UK will give Australia “complete, welded power units” which do not require refuelling over the lifetime of the submarine. In this, we’re following the US model, where each submarine is powered by a reactor with fuel built in. When nuclear subs are decommissioned, the reactor is pulled out as a complete unit and treated as waste. An official fact sheet about this deal states Australia “has committed to managing all radioactive waste generated through its nuclear-powered submarine program, including spent nuclear fuel, in Australia”. What does this waste look like? When Virginia-class submarines are decommissioned, you have to pull out the “small” reactor and dispose of it. Small, in this context, is relative. […]

Australia’s first road made using recycled coffee cups

A suburban road in Penrith has become the first in Australia, to include recycled coffee cups in its construction. The fibres in the cups are a valuable additive that helps create a superior, more durable product, quieter and safer than regular asphalt. The more sustainable asphalt, known as PAK-PAVE™ Roads, has been developed by State Asphalts NSW in conjunction with Closed Loop Environmental Solutions who operate the Simply Cups paper cup recycling program. The development of PAK-PAVE™ Roads was facilitated through the Commonwealths Cooperative Research Centres Program Grant, involving the University of NSW and has been sanctioned by the NSW EPA and Transport NSW. The pilot project for PAK-PAVE™ Roads will take place along a section of Jamison Road at South Penrith, to be followed soon after by a second at Swallow Drive, Erskine Park. These two projects will utilise over 135,000 recycled paper cups including coffee cups, which is 85% of the paper cups collected for recycling in the Penrith LGA in 2022. In addition to the recycled paper cups, the two PAK-PAVE™ Roads will utilise other recycled materials including the equivalent of 1.2 million glass stubbies, together with Reclaimed Asphalt Pavement, Steel Furnace Slag. Collectively, these materials will comprise more than 50% of the materials used. Sustainability benefits of the PAK-PAVE™ Roads include: Using recycled paper cups as a beneficial additive Improved pavement durability and crack resistance Improved wet weather skid resistance and reduced noise levels from surface texture Improved durability of Stone Mastic Asphalt allows thinner surfacing of roads; where thickness can be reduced the cost per m2 of pavement is also reduced Less raw materials are required 24% reduction in carbon footprint These PAK-PAVE™ Roads in Penrith are true examples of the circular economy in action, where items that were once destined for landfill have been […]

Women breaking down barriers in engineering

Engineering has long been a male-dominated field, but in recent years, women have been breaking down barriers and making significant contributions to the industry. Australian owned and operated Humiscope, who specialise in controlling indoor environments through energy-efficient solutions, is one example of this progress. However, despite the increasing number of women joining the engineering industry, there is still a significant gender gap. According to the latest statistics from the Australian Bureau of Statistics, only 14% of engineers in Australia are women. This is a concerning figure, particularly when compared to the number of women studying engineering at university. In 2020, 22% of bachelor\’s degree students in engineering were women, which suggests that there is a significant drop-off in the number of women pursuing engineering careers after graduation. There are several reasons for this disparity. One factor is the lack of female role models in the industry. When young women don’t see themselves represented in the field, they may be less likely to consider engineering as a career. Another is that many people are unaware of the myriad industries in which engineering can be applied and the diverse avenues that can be undertaken when studying engineering. In celebration of World Engineering Day, Humiscope champions the importance of recognising women in the field of engineering and wants to showcase the three female engineers on its team. Ladan Bage, a mechanical engineer with a Masters of Science in Mechanical Engineering, works on several large projects for Humiscope. Ladan offers practical mechanical designs while always considering a client’s requirements. She specialises in drafting, documentation, mechanical design, reverse engineering, manufacturing, and its supervision. Ladan works closely with Paula Andrea Gil who is a drafts(wo)men, with a Bachelor’s Degree in Architectural Drafting and Design and over six years’ hands-on experience. Highly skilled in BIM modelling, Paula […]

New process extracts silicon from solar panels to build better batteries

Researchers have developed a sustainable and highly lucrative way to address two big issues in the clean energy transition, reclaiming one of the most valuable elements from end-of-life solar panels and reconfiguring it to build better batteries. More than 100,000 tonnes of end-of-life solar panels are estimated to enter Australia’s waste stream by 2035. Scientists from Deakin University’s Institute for Frontier Materials (IFM) have successfully tested a new process that can safely and effectively extract silicon from old solar panels, then convert it into a nano material worth more than $45,000 per kilo. This nano-silicon is then mixed with graphite to develop a new type of battery anode shown to increase lithium-ion battery capacity by a factor of 10, a critical breakthrough in energy storage technology. Lead researcher Dr Md Mokhlesur Rahman said that for Australia (and the world) to address the enormous issue of solar panel waste and develop a successful recycling program to divert it away from landfill, scientists must find a way to harvest and repurpose the panels’ most valuable components. “Solar panel cells are fabricated using high-value silicon, but this material cannot be re-used without purification, as it becomes highly contaminated over the 25 to 30 years of the panel’s life,” Dr Rahman said. “We have developed a process that returns silicon collected from used cells to greater than 99 per cent purity, within a day and without the need for dangerous chemicals. This thermal and chemical process is far greener, cheaper, and more efficient than any other technique currently on the market.” But it’s the next step that’s the real game-changer. The Deakin process then takes this regular-sized purified silicon and reduces its size to nanoscale using a special ball-milling process. Again, without the need for toxic chemicals. “We are using that nano-silicon to develop […]

Reducing plastic waste at Christmas

A world-first open platform to help reduce plastic waste and encourage sustainable solutions is being launched in time for the biggest waste dump of the year – Christmas. With approximately 30 per cent more waste produced at this time of year, now is the perfect time to start. I’M PLASTIC FREE www.implasticfree.com is a free platform to find eco services and products for consumers and businesses and provides up-to-date independent research – no greenwashing – and information for living more sustainably and ethically. Its values are simple: all materials and products are treated with value, and the circular economy is an integral part of our everyday life. ‘If every person made one or two easy changes using eco-friendly materials instead of single-use plastics, the impact would be enormous,’ says founder, Simona Paganetto. ‘Reuse and repurpose are first so there’s no waste, but when it’s time to replace your item, we provide a platform that makes finding and choosing an alternative easy.’ At Christmas this can really add up. Australians use an average of eight metres of paper for Christmas gifts. That might not sound like much, but it adds up to around 150,000 kilometres of wrapping paper. Enough to circumnavigate the globe four times. ‘We’re talking about something that is just ripped away and discarded, and if it’s got any type of foil or shine on it, it can’t be recycled,’ says Simona. ‘Don’t forget the ribbon and tinsel too, which are made from plastic.’ A different approach can make a huge difference. ‘Firstly, reusing paper, ribbon and tinsel is great,’ she says, ‘but if you don’t have any to reuse, there are many alternatives.’ I’M PLASTIC FREE has a handy Christmas checklist to help. ‘If every Australian family wrapped just a quarter of their presents in reused or alternative-paper […]

How digital technologies will help sustain the health of construction projects

Rob Bryant, EVP of APJ at InEight Project health is constantly buffeted by risk events from all sides. And projects in Australia are being crippled by a trifecta of weather, supply chain disruption and increasing input costs. Working through another La Niña season, the wet weather will loom over the construction sector as projects will once again be delayed and subsequently run over budget because of persistent and unusual weather. Hence, it is no surprise the latest InEight Global Capital Projects Outlook reveals there is a 11% higher concern over climate change from 2021 to 2022. Managing risk, improving efficiency, and determining more predicable outcomes are all strategies to help reign in those factors and bring about a sense of wellbeing in a project landscape that is littered with chaos mines. Developments in digital technologies enable solutions such as artificial intelligence (AI) and enhancements to Critical Path Method (CPM) provide timely forecasts, reliable predictions, and effective risk management in the face of changing factors, whatever the weather. How can AI support risk management Although AI is not some magic tool whereby a contractor pushes a button and generates a schedule, it can be leveraged and manipulated to provide more realistic, dependable suggestions. In effect, it improves the planning process by enabling a computer to mimic the way a human makes decisions. An inference engine is a component of the AI system that applies logical rules to the knowledge base to deduce new information. When a project owner asks for a suggestion, the inference engine requests inputs in order to understand the context, such as the type of project, location, quantities and other variables. It then uses those variables to understand context, interrogate the knowledge library and provide suggestions. To fully capitalise from the benefits of AI, project leaders are provided […]

Decarbonise while you Digitalise

Nathan Knight, Hitachi Vantara’s Managing Director for Australia and New Zealand, makes the case for a coordinated approach to decarbonisation and digitalisation. Imagine that manufacturers have a character on each shoulder, one with the word PROGRESS emblazoned across its chest, and the other, SUSTAINABILITY. When deciding where to invest precious resources like time, expertise and money, they can feel like two competing priorities. “Pick me,” says Progress. “More digital services, more automation, more cloud, more diversification, more data analytics, more!” The other voice pleads, “But what about me? You have to consider the planet, responsible resource management, diversification of your staff and your supply chain. You have to reduce your emissions.” Sustainability’s voice is getting louder and more insistent. In the pursuit of digitalisation in the name of progress and competitive edge, the two do not have to be at odds with one another. In fact digitalisation is a powerful tool that can help manufacturers achieve the critical sustainability goal of decarbonisation. Many Eyes on the Manufacturing Sector Australia strengthened emissions reduction targets with the goal of net zero by 2050. According to Grattan Institute, decarbonising Australian industry is an “industrial revolution against a deadline” and the scale and pace of change required is unprecedented. The think tank has called for government policy change, stricter emissions limits and a focus on decarbonising heavy manufacturing and mining, which reportedly produce a third of Australia’s carbon emissions. The heavy industry sector collaborated with decarbonisation experts to form the Australian Industry Energy Transitions Initiative (ETI), which says that regional Australia’s industrial economy could cut greenhouse gas emissions by more than 80% and become centres for multibillion-dollar investments in renewable energy. It would take an unprecedented transformation of the energy system, they say. Acknowledging that the agriculture, mining, manufacturing, data centre and other sectors […]
